The serum iron level is low in iron deficiency and inflammatory anaemia because it depends on efficient recycling of iron through macrophages and the bone marrow. In iron deficiency, there is insufficient iron for iron recycling, while in inflammatory anaemia, increased hepcidin levels result in iron trapping in macrophages.

Haematinics are the nutrients needed by the bone marrow to make blood cells in the process of haematopoiesis. Without adequate amounts of these nutrients, cytopenia(s) and related symptomscan develop. Excess amounts can also be pathological and can point to various underlying disease states. This guide to haematinics interpretation will focus on de...
Investigating a patient’s iron status can become complicated as no single testaccurately represents all stages of iron metabolism and some of the available tests can be affected by inflammation and renal disease. Given how common iron deficiency anaemiais, it is important to understand the tests used to investigate iron deficiency and how to interp...
Testing for a patient’s vitamin B12 and folate statusis challenging as existing investigations are not sensitive or specific and show wide variability between different laboratories. For this reason, routine screening is not indicated for any patient group. Instead, investigations should be performed in response to specific clinical indicators. As ...
Folate is the term for all biological forms of vitamin B9, whilefolic acid refers to the synthetic formused for treatment. Both forms are absorbed in the terminal ileum, and half of the body’s folate is found in the liver. It is often measured simultaneously with vitamin B12 as they share a close relationshipin human metabolism with similar clinica...

May 7;372(19):1832-43.Jun 15, 2017 · What you need to know. •Iron overload typically results in a high ferritin and transferrin saturation. •Iron deficiency is best assessed using serum ferritin, which is low in the absence of inflammation. •Ferritin levels can be elevated by inflammatory processes and can mask iron deficiency.
In general, a ferritin level of less than 15 micrograms/L is considered indicative of absent iron stores, while levels of less than 30 micrograms/L are generally indicative of low body iron stores. The lower limit of normal for most laboratories, therefore, lies in the range of 15–30 micrograms/L [ Snook, 2021 ].
